Molly spread the blueprints across the table, knocking over a juice box. "So the bouncy castle is here," she said, jabbing a finger at the paper. "That's our entry point." Bill squinted. "We're infiltrating through a bouncy castle?" "It's genius. Nobody suspects a grown adult flopping around in there." "Molly, I'm forty-three. My knees can't handle that." "Then wear pads," she snapped. "Now, the presents are stacked near the cake table. We grab everything, stuff it in garbage bags, and walk out." Bill scratched his chin. "What about the clown?" "What clown?" "Every kid party has a clown. He'll see us." Molly waved her hand dismissively. "We bribe him with cake." "You can't bribe a clown with cake. They're professionals." "Everyone has a price, Bill." He leaned back, crossing his arms. "This is insane. We're stealing from children." "Rich children," she corrected. "Their parents bought a pony." Bill blinked. "There's a pony?" "Focus!" Molly slapped the table. "We're in, we're out, we're millionaires." "From action figures and friendship bracelets?" "It's the principle of the thing." Bill sighed, defeated. "Fine. But I'm not wearing the knee pads." Molly grinned wickedly. "You'll wear them. And you'll love them."
